This program tests the following fault tolerant naming service implementation
use cases:
1) Failover: Validate that a client can seamlessly connect to the alternate
server of a server naming server pair after the other server has been
terminated.
2) Persistence: Validate that repository data written by the naming service is
available upon startup.
3) Equivalence: Validate that a client can seamlessly invoke naming operations
on either server instance.
================================================================================
Failover Test
================================================================================
<hostname> = <local_host>
<port1> = <first unused port>
<port2> = <second unused port>
1) Create empty NameService and GroupService directories
cd $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant
mkdir NameService
mkdir GroupService
2) Start primary tao_ft_naming process
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming --primary \
-ORBListenEndPoints iiop://<hostname>:<port1> \
-m 0 \
-r NameService \
-v GroupService &
3) Start backup tao_ft_naming process
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming --backup \
-ORBListenEndPoints iiop://<hostname>:<port2> \
-m 0 \
-c $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/ns.ior \
-g $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/nm.ior \
-r NameService \
-v GroupService &
4) Terminate primary tao_ft_naming process
5) Run client with failover argument
client --failover \
-p file:///$TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/ns.ior \
-r file://$TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/nm.ior \
-b 4 -d 4
==============================================================================
Example Output:
==============================================================================
INFO: Failover Name Test OK
INFO: nm1ref: file:///tmp/ramdisk/tmp/nm.ior
INFO: Object Group Found In Repository
INFO: Failover ObjectGroup Test OK
6) Cleanup
rm -rf NameService
rm -rf GroupService
================================================================================
Persistence Test
================================================================================
<hostname> = <local_host>
<port1> = <unused port>
1) Create empty NameService and GroupService directories
cd $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant
mkdir NameService
mkdir GroupService
2) Start tao_ft_naming
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming \
-ORBListenEndPoints iiop://<hostname>:<port1> \
-g $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/nm.ior \
-o $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/ns.ior \
-v GroupService \
-u NameService &
3) Start test object server
server -ORBDefaultInitRef corbaloc:iiop:<hostname>:<port1> \
-o $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/srv.ior &
4) Run the test client with the persistence and create arguments
client --persistence --create \
-p corbaloc:iiop:<hostname>:<port1>/NameService \
-r corbaloc:iiop:<hostname>:<port1>/NamingManager \
-b 4 -d 4
==============================================================================
Example Output:
==============================================================================
INFO: Persistence Creation Name Test OK
INFO: Object Group BasicGroup Found In Repository
INFO: validating group member location1
INFO: object group member at location1 reports location1
INFO: validating group member location2
INFO: object group member at location2 reports location2
INFO: validating group member location3
INFO: object group member at location3 reports location3
INFO: validating group member location4
INFO: object group member at location4 reports location4
INFO: validating group member location5
INFO: object group member at location5 reports location5
INFO: validating group member location6
INFO: object group member at location6 reports location6
INFO: Persistence Creation ObjectGroup Test OK
5) Terminate tao_ft_naming and then restart it with the original arguments
kill `pidof $TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming`
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming \
-ORBListenEndPoints iiop://<hostname>:<port1> \
-g $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/nm.ior \
-o $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant/ns.ior \
-v GroupService \
-u NameService &
6) Now run the test client with the persistence and valdiate arguments
client --persistence --validate \
-p corbaloc:iiop:<hostname>:<port1>/NameService \
-r corbaloc:iiop:<hostname>:<port1>/NamingManager \
-b 4 -d 4
==============================================================================
Example Output:
==============================================================================
INFO: Persistence Validation Name Test OK
INFO: Object Group BasicGroup Found In Repository
INFO: validating group member location1
INFO: object group member at location1 reports location1
INFO: validating group member location2
INFO: object group member at location2 reports location2
INFO: validating group member location3
INFO: object group member at location3 reports location3
INFO: validating group member location4
INFO: object group member at location4 reports location4
INFO: validating group member location5
INFO: object group member at location5 reports location5
INFO: validating group member location6
INFO: object group member at location6 reports location6
INFO: Persistence Validation ObjectGroup Test OK
7) Cleanup
rm -rf NameService
rm -rf GroupService
================================================================================
Redundant Equivalancy Test
================================================================================
<hostname> = <local_host>
<port1> = <first unused port>
<port2> = <second unused port>
1) Create empty NameService and GroupService directories
cd $TAO_ROOT/orbsvcs/tests/FT_Naming/FaultTolerant
mkdir NameService
mkdir GroupService
2) Start primary tao_ft_naming process
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming \
--primary \
-ORBListenEndPoints iiop://<hostname>:<port1> \
-o /tmp/ns_primary.ior \
-h /tmp/nm_primary.ior \
-r NameService \
-v GroupService &
3) Start backup tao_ft_naming process
$TAO_ROOT/orbsvcs/FT_Naming_Service/tao_ft_naming \
--backup \
-ORBListenEndPoints iiop://<hostname>:<port2> \
-o /tmp/ns_backup.ior \
-h /tmp/nm_backup.ior \
-c /tmp/ns_multi_profile.ior \
-g /tmp/nm_multi_profile.ior \
-r NameService \
-v GroupService &
4) Now run the test client with the equivalence argument
client --equivalence \
-p file:///tmp/ns_primary.ior \
-q file:///tmp/ns_backup.ior \
-r file:///tmp/nm_primary.ior \
-s file:///tmp/nm_backup.ior \
-b 4 -d 4
==============================================================================
Example Output:
==============================================================================

INFO: ns1ref profile count: 1
INFO: ns2ref profile count: 1
INFO: Equivalence Name Test OK
INFO: nm1ref: file:///tmp/nm_primary.ior
INFO: nm2ref: file:///tmp/nm_backup.ior
INFO: nm1ref is not equivalent to nm2ref
INFO: nm1ref profile count: 1
INFO: nm2ref profile count: 1
INFO: Primary Found Object Group test_group_1 Created By Primary In Repository
INFO: Backup Found Object Group test_group_2 Created By Backup In Repository
INFO: Primary Found Object Group test_group_2 Created By Backup In Repository
INFO: Backup Found Object Group test_group_1 Created By Primary In Repository
INFO: Equivalence ObjectGroup Test OK
5) Cleanup
rm -rf NameService
rm -rf GroupService
